Review: Easy, Clean, and Effective Concrete Crack Filler for Targeted Repairs - The Red Devil 0645 Concrete Repair Patch is one of the most practical, no‑nonsense crack fillers you can keep on hand for fast structural touch‑ups. The pre‑mixed formula is the real advantage here—no measuring, no dust, no mixing ratios to get wrong. You squeeze it out, tool it into place, and it immediately behaves like a proper cementitious filler rather than a thin caulk. It adheres well to concrete, masonry, mortar, and even works for filling small holes in stucco, making it a versatile repair option for both interior and exterior surfaces. Once cured, it dries to a hard, sandable finish that blends cleanly with surrounding material. For hairline cracks, it flows smoothly enough to fill without shrinking; for wider gaps, it layers without slumping. The 5.5‑oz tube is ideal for targeted repairs like steps, patio cracks, foundation lines, garage floor blemishes, and small stucco imperfections where a full bag of patch mix would be overkill. Cleanup is simple with water while still wet, and the cured patch accepts paint without flashing or discoloration. If you need a reliable, ready‑to‑use filler that performs like a small‑scale concrete patch without the mess of mixing, this tube delivers consistent, repeatable results. Review: Red Devil 0641 Concrete Repair Patch, Cement Crack Filler, Pre-Mixed, 1 Gallon - Going to be needing another tub if this AWESOMENESS! We just moved into this house not long ago and the garage floor was pitted and flaking and doing all sorts of other crazy things. I was bound snd determined to at least fill the low spots in but didnt have a clue what to use. I came across this stuff here on desertcart and thought I wouldntry it. Worked beautifully. I still have a few pits to fill in, dont want a completely smooth floor as I want it rough like to look like a medieval floor. That garage is getting closed in and made into a huge pantry with butcher block island and shelves out the ying yang, so, yesh, this stuff fills too deep pits but keeps the rough aged look Im wanting. Anyway! Love this product! Was so easy to lay down, not messy at all ## Features - REPAIRS CRACKS AND BREAKS IN CONCRETE: Premixed formula makes repairs easy - DRIES A LIGHT TO MEDIUM GRAY COLOR: Ideal for lighter shades of concrete - WON'T SHRINK OR CRACK: Provides maximum flexibility for a permanent repair - INTERIOR OR EXTERIOR USE: Can be used inside or outside - WATER CLEAN UP: Cleans up easily with soap and water.

We just moved into this house not long ago and the garage floor was pitted and flaking and doing all sorts of other crazy things.

Was so easy to lay down, not messy at all ### ⭐⭐⭐⭐ Good Product - Read My Tips For Using It *by T***Y on October 26, 2025* Seems like a good product when you don’t want to hassle with mortar/cement mix. Agree with one reviewer who said product doesn’t come out of the tube without a good bit of effort. I think this is partly due to the water content in this pre-mixed variety, which seems pretty low. I didn’t add any water before applying and I also decided to use my fingers to work it into the block foundation I was repairing. That work nicely, much better than the spackle knife/trowel. My trick to get the product out of the tube if you have trouble is this, cut the nozzle as close to the main tube body as you can, use your foot with a shoe or boot on and then slowly apply pressure and product will easily dispense with your weight. I then used my fingers as needed to apply, but you could try applying with a tool. I just found that not great with this mix and cleanup is easy with water so no worries. I did detect a smell of slight acetone or something, I assume something which makes the cement more pliable to get it out of the tube. It’s not real strong but it is there. I would buy this again. I used 3-4 full tubes on my project and since I bought the 12 pack, I have several left. I would recommend using a whole tube at a time as concrete could be very tough to work with after recapping. I have a trick there too. I always take a little cling wrap and put it over the nozzle, then put a small rubber band around that toward where the nozzle meets the tube, only then do I cap it. That seems to typically keep all my tube caulk/cement pliable a long time after resealing. Hopefully product will dry fully and give me many good years of secure foundation. ## Frequently Bought Together - Red Devil 0645 Concrete Repair Patch, Cement Crack Filler, Pre-Mixed, 5.5 Oz.
